BufferedReader can buffer more data from the socket than you've read yet. So on the client side, the header of your byte[] has probably already been read and buffered by your inFromServer reader, and will not be available to your ObjectInputStream.

Don't do that kind of thing. Either do all your marshaling "manually" (using the PrintWriter/BufferedReader pair), or do it all with object serialization with ObjectOutputStream/ObjectInputStream.
